Strap for Portugieser Yacht Club Worldtimer Stainless Steel / Solaris

The lug width of the IWC Portugieser IW3266-06 is 22 millimetres. This measurement represents the internal distance between the two lugs where the watch strap bars are inserted. To verify compatibility, measure the available space using a digital calliper or ruler; the result should fall between 21.8 and 22.2 millimetres.

The choice of strap depends on intended use and personal aesthetic preferences. For a classical interpretation, we recommend dark brown alligator or vegetable-tanned calf leather, which create elegant contrast with the steel case and develop natural patina over time. Shell cordovan offers superior material density and a rich tactile sensation. For those prioritising versatility, a heavy canvas NATO strap or FKM rubber strap provides robust and informal options.

Strap change is accomplished by extracting and inserting the spring bars that connect the strap to the case. Remove the old strap by exerting light pressure on one spring bar downwards using the dedicated extraction tool; then insert the new spring bar into the wider hole of the lug. We recommend entrusting this operation to a professional watchmaker to avoid damage to the lugs.

Numerous high-quality aftermarket options are available in the 22mm size. Specialised artisans such as Casati Milano craft custom straps in alligator, calf leather, shell cordovan and other materials, ensuring precision in assembly and customisation of finishing details (initials, thread colour, buckle type). Online retailers also offer pre-made straps from numerous manufacturers with rapid shipping times.

The lifespan of a leather strap varies according to material, frequency of use and environmental conditions. A high-quality calf leather strap typically lasts 3–5 years with daily wear; shell cordovan, due to its superior density, may last 7–10 years. Alligator strap longevity falls between these two. Exposure to UV rays, excessive moisture and perspiration accelerate wear; proper maintenance (periodic cleaning and conditioning) significantly extends longevity.
